NIST
Standard Reference Database 1A
NIST/EPA/NIH
Mass Spectral Library with Search Program: (Data Version: NIST 08,
Software Version 2.0f)
This database
is the product of a multiyear, comprehensive evaluation and expansion
of the world's most widely used mass spectral reference library.

Evaluation
and Quality Control
- Each
spectrum critically examined by experienced mass spectrometrists.
- Each chemical
structure examined for correctness and consistency, using both human
and computer methods.
- Spectra of
all stereoisomers intercompared.
- Chemical
names examined by experts and IUPAC names provided.
- Thousands
of replacements of spectra with a higher quality spectra.
- Verified
CAS registry numbers.
This library
is available with Version 2.0f of the full-featured NIST MS Search
Program for Windows, which also includes integrated tools for:
- GC/MS deconvolution
(AMDIS version 2.66)
- Interpretation
of mass spectra (MS Interpreter version 2.0, a thermodynamics-based
interpreter of fragmentation)
- Chemical Substructure
Identification
New features
of the NIST
MS Search Program are:
- A spectrum
search for MS/MS spectra in MS/MS libraries
- A search
for information in the Contributor/Comment field which may be particularly
useful for certain types of information relevant to MS/MS spectra
- Flexibility
in using Name fragments in Constraints that allows specifying the
presence or absence of arbitrary parts of a name
- Five new constraints
that permit additional types searches

An Automated MS Deconvolution and Identification System (AMDIS)
This program extracts
the spectrum of each component in a mixture analyzed by GC/MS and identifies
target compounds. With the support of the Defense Special Weapons
Agency (DOD), it was developed at the National Institute of Standards
and Technology (NIST) for the critical task of verifying a major
international treaty, the Chemical Weapons Convention. After
two years of development and extensive testing it has been made available
to the general analytical chemistry community.
